Compare a `basic_const_iterator` with another value. These function templates are used when the left operand is not a `basic_const_iterator`.

I satisfies the exposition-only concept /*not-a-const-iterator*/ if and only if it's not a specialization of `basic_const_iterator`.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when basic_const_iterator<Iter> is an associated class of the arguments.

### Parameters

x, y | - | iterators to compare

### Return value

1) x < y.base()
2) x > y.base()
3) x <= y.base()
4) x >= y.base()

### Notes

If the left operand is a `basic_const_iterator`, the member comparison functions are used.

### Example

Run this code

    #include <iterator>

    int main()
    {
        static int arr[1];
        static constexpr std::basic_const_iterator<int*> it = std::end(arr);
        static_assert(arr < it);
    }
